And that reason is that RAID card manufacturers want to take every dime you have.

There was a time when the ''real'' RAID was the only ''real'' solution. Not so anymore.
The performance difference between software raid and hardware raid is so small that it is barely even noticeable on any modern(read: >2GHz) workstation/server(read: multi-processor) system under normal workloads/conditions.
( Of course, that changes when concurrent access goes into hundreds-thousands and/or file sizes are > total system memory. )

You can run your tests but I ran mine and the results are very clear. NVRAID does just fine for normal workstation usage. I'd be a lot happier if it had a stripe of mirrors(1+0) rather than mirror of stripes(0+1) for what they mislabeled as RAID 10 but it still provides fault tolerance.
